ok plane has 3 retractable undercarriages... all being powered by one retract servo

In this case I think its easier to have one servo per retract.


will 3 less powered servos equal one strong servo being used for 3.... or do all 3 need to be strong servos?

Ie.. is a 3.4kg torque servo enough for to operate one retract in a 90 size plane.?
